I'm uploading these files as I complete them. The entire book (the main chapters, at any rate) will eventually be available. Enjoy!
In the meantime (and for notes on the chapters and suggestions of further reading), the entire text is available as a free download from http://www.thepublicdomain.org/download/, or for purchase at your favourite bookstore for US$28.50 (ISBN: 978-0-300-13740-8).

Note: My apologies that this project has stagnated somewhat on account of various personal time-constraints. I'm currently recording and uploading chapters from Doctorow's "Context", and when that's completed I intend to return to this project and see it through.
